the fronds ; but, as Don does not mention the venation, and says—

pinnae. Whether the present fern ought to be called P. paludosum , or by one 
of Wallich’s three or four names, is a point that perhaps may never be settled ; 
but that it is distinct from P. distans , Don, cannot, I think, be questioned. 
In the difficulty Wallich created by not attending to the nature of the rhizome, 
and by giving so many names to his specimens, it seems advisable 
to give a new name to those that cannot reasonably be put under 
P. distans .
